' ADJUSTABLE SUPPORT FOR VAPOR-LAMPS.

' Speciflcation'of Letters Patent.

1905. Serial No. 240,272.

of New Jersey, have invented certain new and useful Improvements in Adjustable Supports for Vapor-Lamps, of which the following is a specification. I

The present invention relates to frames for vapor electric lamps such as are repre-.

sented'by the well-known mercury vapor lamps now in common use.

The special object of the'invention is to provide means whereby the starting of such lamps may be readily accomplished either singly or in groups by means of tilting apparatus in which connection is first made between the negative and positive electrodes through a stream or column of mercury, and afterward such connection is broken by a proper manipulation of the apparatus, so that the current which originally flowed through the mercury column or stream shall pass through the vapor path between the main positive and the main negative electrodes. It has been found in practice that a variety of tilting frames is required for various purposes, whether for photographing by means of mercury vapor lamps, or

for printing, enlarging or,copying, as the case may be.

This application is a division of my ap 1ication filed July 28, 1904, Serial Num er 218,473, and relates to a special application of the invention therein described and shown.

In the drawings, Figures 1 and 2 are, re-

spectively, front and side elevations of an apparatus particularly adapted for photographic work.

Referring to the drawings, the lamps, 2, 2, shown in Fig. 2 are adapted to operate in a substantially vertical position. These lamps are mounted in a frame 1 pivoted at 3 in a standard, 4. The frame 1 is open starting and for the purpose 0 at the front, as shown, and is preferably solid at the back where the pivot 3 is attached.

' The special feature of this apparatus is that the lamps mounted as shown and described can be tilted for the urpose of i being -re stored to operative position, without interfering with any surfaces, either photographic or printing surfaces, which are placed in their normal position in front of the lamps, or which may be placed in holders attached to the lamp frames themselves. In other words, the lamps are not tilted forward and backward, as regards their line of radiation, but are tilted sidewise and restored to operative positionin the same general direction.

At 5 I show a handle for enabling the operator to move the frame easily and at 6 and 7, respectively, I show a latch and detent arrangement whereby the apparatus is held in its vertical position when restored after being tilted in reverse directions.

At 8 is shown an elastic stop secured to an upright, 9, for relieving all shock when the apparatus is restored to operative posi tion. 1

I claim as my invention The combination with a vapor electric lamp, of a vertical frame within which the said lamp is mounted, a standard, and a pivot for the said frame mounted in the said standard, means whereby the frame can be moved in a plane parallel to the front of the frame and a cushion for relieving Patented Sept. 15, 1914.
